ANSWER

Speed of light in A=2.25×10

8

m/s

Speed of light in B=2×10

8

m/s

optional density ∝

speed of light

1

∴ Medium B will be optically denter than A.

The higher the density, the more molecules there are per unit volume, and the more light obstructed. Therefore, refraction index also increases.
